Adobe have just published the Camera RAW release candidate 5.5 and the DNG converter 5.5, both of which add support for the Nikon D300S, D3000, Olympus E-P1 and the Panasonic DMC-FZ35.ACR 5.5 and DNG Converter 5.5 can be downloaded for free from the Adobe Labs website. For more about the DNG converter, take a look at this article.All versions of ACR from 5.0 on are ONLY compatible with CS4. Do NOT install incompatible ACR plugins in your plugins folder or there will be serious trouble! If you need to convert RAW files from new cameras for use in previous versions of ACR, get the DNG Converter instead. It can be dowloaded from the same Adobe Labs page.For a complete compatibility overview of Nikon Cameras, Adobe Camera RAW and DNG, take a look at my Nikon/ACR/DNG compatibility chart (PDF 60 Kb.).
